One other thought. Ink does not last forever. Might be wise to replace all your colors, not just the black, and manually clean out the lines, head, whatever has had ink setting in it for 5 years (if you left it inked-up). I've had sublimation ink go bad in a bit over a year ... then no choice but to manually clean everything out and hope for the best. Permanently lost one nozzle on the head.
